Gold Cyanide an overview ScienceDirect Topics

Gold is added as potassium gold cyanide, and some free potassium cyanide and carbonate exists. Phosphates and hydroxides can be added to improve conductance. When gold content is 8 g l −1 or more, the cathodic current efficiency is almost 100%, but often gold content is kept lower due to the drag-out losses.

The Metallurgy of Cyanide Gold Leaching Core Resources

Nature of Gold: The surface of a gold particle will typically be dissolved at a rate of around 0.2-0.5 µm of surface depth per hour in a cyanide leach. For large gold particles and nuggets, this is too slow to be fully dissolved in a typical processing plant. Much simpler and less expensive gravity methods are available to recover this gold.
